I just want to know most major differences between a computer keyboard and a typewriter?

While a computer keyboard and a typewriter keyboard look very similar, they work in very different ways. A computer keyboard generally allows a user to type letters into a computer and these letters are then displayed on the screen. Of course, the computer can usually print these letters onto a paper, but the keyboard itself does not print the letters in actual ink. Keys on the computer keyboard rely on electronic circuits which are translated by the computer into letters. A typewriter keyboard is far more direct. This type of keyboard does not complete a circuit but rather moves mechanical parts (of course, some newer typewriters do use an electronic circuit, but that circuit still moves a mechanical part rather than sending a signal to a computer). A typewriter keyboard generally allows the user to print ink letters directly onto a piece of paper. The keys usually activate a hammer or turn a circular device covered in letters. Then, the key causes the mechanism to be pressed against an ink strip which presses the corresponding letter onto a page. Both keyboards fulfill the same function, to allow the user to type out letters.

type writers are less expensive and are made by different people. they also both look very different and a type writer is not very popular, and has no screen. also a type writer can only type, while a computer can do many things,in contacting friends or learning things
